Two strains, identified as Rhodococcus wratislaviensis IFP 2016 and Rhodococcus aetherivorans IFP 2017, were isolated from a microbial consortium that degraded 15 petroleum compounds or additives when provided in a mixture containing 16 compounds (benzene, toluene, ethylbenzene, m-xylene, p-xylene, o-xylene, octane, hexadecane, 2,2,4-trimethylpentane [isooctane], cyclohexane, cyclohexanol, naph...

The simulated moving bed (SMB) process has been extensively used in industrial separations for binary and pseudo-binary separations. In pseudo-binary mixtures because the desired component is the most or least retained, the other components do not have to be separated. The UOP Parex process for p-xylene purification is an example. When non-target components have similar adsorption behaviors, th...

With the help of pharmacophore analysis and docking investigation, 15 novel 1-(4,4,5,5-tetramethyl-2-(3-nitrophenyl)-4,5-dihydroimidazol-1-yl)-oxyacetyl-L-amino acids (6a-o) were designed, synthesized, and assayed. On tail-flick and xylene-induced ear edema models, 10 μmol/kg 6a-o exhibited excellent oral anti-inflammation and analgesic activity. The dose-dependent assay of their representative...

background: benzene, toluene, ethyl benzene and xylene compounds (btex) are very dangerous in terms of health and environmental and have high toxicity in aquatic environment. the purpose of this study was to investigate the performance analysis of petroleum hydrocarbons xylene using solar radiation uv/tio2 method in industrial synthetic waste . methods: an experimental-interventional study was ...

High selectively catalytic conversion of lignin-based phenols (m-cresol, p-cresol, and guaiacol) into para-/m-xylene was performed over Pt/HZSM-5 through hydrodeoxygenation and in situ methylation with methanol. It is found that the p-/m-xylene selectivity is uniformly higher than 21%, and even increase up to 33.5% for m-cresol (with phenols/methanol molar ratio of 1/8). The improved p-/m-xylen...

In a chemical plant, 40%–60% of energy and capital cost is tied to separation processes. As such, these processes must be selected carefully. Separation process can classified as thermal or non-thermal. Recent literature suggests that such distillation are inherently intensive relative their non-thermal counterparts membrane separation. The reasons for this claim traced back the success reverse...

BDH xylene substitute, a terpene-based product, and its mixture with anhydrous alcohol were found to be excellent replacements for xylene and carbol-xylene, respectively, in the trichrome staining technique applied to sodium acetate-acetic acid-Formalin-fixed fecal smears for detection of intestinal protozoa.

OBJECTIVE To assess the extent of exposure for Volatile Organic Compounds (VOCs) among nonoccupationally exposed commuters in Mexico City. MATERIAL AND METHODS Blood concentrations of benzene, toluene, ethylbenzene, m-/p-xylene, o-xylene and methyl tert-butyl ether were determined on samples collected from participants after the morning commute. RESULTS Median blood concentrations of benzen...
